Acceleration/Previewing/Vocabulary: abacus, mechanical/analog Eniac/vaccum tube/digital transistor, integrated circuit, PC
Teaching Strategies and Distributed Guided Practice/Summarizing Prompts: Structured note taking (Flowchart timeline)
1. Show abacus(aided in counting, digital mechanical device)
Structured note taking (Flowchart timeline)
1. Show abacus(aided in counting, digital mechanical device)
- Lower deck (each bead value=1)
- Upper deck (each bead value=5)
*2. Demo Mechanical calculator(relied on gear movement and readout)3. Vacuum tube(show examples)
- Switch with no moving parts
- Large and burn out (light bulb)
*4. ENIAC (17,468 tubes) digital/electric/binary5. Transistors/Integrated circuit
- Smaller switches (with no moving parts)
- Reliable, bunched together to create integrated circuits to perform repetitive tasks
6. Result - computers became smaller, faster, less expensive and more reliable
